Referring to
Step 21: A terminal determines a scheme used for uplink transmission.
In this embodiment, the scheme used for the uplink transmission may be understood as a scheme supported by a waveform used for the uplink transmission. The waveform includes, but is not limited to, a discrete Fourier transform (DFT) waveform, a cyclic prefix (CP) waveform, and the like. The DFT waveform is, for example, a discrete Fourier transform-spreaded OFDM (DFT-S-OFDM) waveform, or the like, which is not limited. The scheme includes, but is not limited to, space division multiplexing (SDM), frequency division multiplexing (FDM), a single frequency network (SFN), and the like.
Step 22: The terminal determines a DMRS port for the uplink transmission according to the scheme.
In this embodiment, the above uplink transmission may include, but is not limited to, physical uplink shared channel (PUSCH) transmission, physical uplink control channel (PUCCH) transmission, and the like.
According to the port determining method in this embodiment of this application, the terminal may determine a scheme used for uplink transmission, and determine a DMRS port for the uplink transmission according to the scheme. Therefore, the DMRS ports can be interpreted from the perspective of a transmission scheme of the terminal, to meet DMRS port indication requirements in different transmission schemes.
Optionally, in this embodiment of this application, if the scheme used for the uplink transmission of the terminal is SDM or SFN, a DMRS port for the uplink transmission may be determined by at least one of the following:
In some embodiments, in the SDM scheme, if a network side indicates that the uplink transmission of the terminal is associated with a plurality of target objects, the terminal may determine, according to the sum of ranks indicated by the plurality of SRI fields received (e.g., all the SRI fields received) or according to the sum of ranks indicated by the plurality of TPMI fields received (e.g., all the TPMI fields received), the first table for interpreting DMRS ports.
In some embodiments, in the SFN scheme, if transmission of the terminal associated with a plurality of target objects has an orthogonal DMRS port and the network side indicates that the uplink transmission of the terminal is associated with a plurality of target objects, the terminal may determine, according to the number of ranks indicated by the plurality of SRI fields received (e.g., all the SRI fields received) or according to the sum of ranks indicated by the plurality of TPMI fields received (e.g., all the TPMI fields received), the first table for interpreting DMRS ports.
In some embodiments, the plurality of SRI fields and/or the plurality of TPMI fields may be carried in downlink control information (DCI), which is sent by the network-side device to the terminal.
In some embodiments, when the terminal determines a first DMRS port for the uplink transmission according to a first table, specifically, the first DMRS port for the uplink transmission is selected from the first table according to an antenna port indicator field received by the terminal. That is, the first DMRS port is a DMRS port in the first table indicated by the antenna port indicator field.
For example, if the sum of ranks indicated by the plurality of TPMI/SRI fields is 2, the first table may be, but is not limited to, shown in Table 1 below:
Referring to Table 1, the Value in Table 1 is related to the antenna port indicator field. For example, a value of the antenna port indicator field may be the Value in Table 1. If the value of the antenna port indicator field is a first value, DMRS ports 0 and 1 from a code division multiplexing (CDM) group may be indicated. For example, the first value corresponds to Value 0. If the value of the antenna port indicator field is a second value, DMRS ports 0 and 1 from two CDM groups may be indicated. For example, the second value corresponds to Value 1. If the value of the antenna port indicator field is a third value, DMRS ports 2 and 3 from two CDM groups may be indicated. For example, the third value corresponds to Value 2. If the value of the antenna port indicator field is a fourth value, DMRS ports 0 and 2 from two CDM groups may be indicated. For example, the fourth value corresponds to Value 3.
In another example, if the sum of ranks indicated by the plurality of TPMI fields is 4, the first table may be, but is not limited to, shown in Table 2 below:
Referring to Table 2, the Value in Table 2 is related to the antenna port indicator field. For example, a value of the antenna port indicator field may be the Value in Table 2. If the value of the antenna port indicator field is a first value, DMRS ports 0-3 from two CDM groups may be indicated. For example, the first value corresponds to Value 0.
In some embodiments, in the SDM scheme, if the network side indicates that the uplink transmission of the terminal is associated with a target object, the terminal may determine, according to the rank indicated by the target TPMI field received, the second table for interpreting DMRS ports.
In some embodiments, in the SFN scheme, if transmission of the terminal associated with a plurality of target objects has an orthogonal DMRS port and the network side indicates that the uplink transmission of the terminal is associated with a target object, the terminal may determine, according to the rank indicated by the target TPMI field received, the second table for interpreting DMRS ports.
In some embodiments, in the SFN scheme, if transmission of the terminal associated with a plurality of target objects has a same DMRS port, the terminal may determine, according to the rank indicated by the target TPMI field received, the second table for interpreting DMRS ports.
In some embodiments, the above target TPMI field is a first TPMI field received by the terminal.
In some embodiments, the above target TPMI field may be carried in DCI, which is sent by the network-side device to the terminal.
In some embodiments, when the terminal determines the second DMRS port for the uplink transmission according to the second table, specifically, the second DMRS port for the uplink transmission is selected from the second table according to an antenna port indicator field received by the terminal. That is, the second DMRS port is a DMRS port in the second table indicated by the antenna port indicator field.
For example, if the rank indicated by the target TPMI field is 2, the second table may be, but is not limited to, shown in Table 3 below:
Referring to Table 3, the Value in Table 3 is related to the antenna port indicator field. For example, a value of the antenna port indicator field may be the Value in Table 3. If the value of the antenna port indicator field is a first value, DMRS ports 0 and 1 from a CDM group may be indicated. For example, the first value corresponds to Value 0. If the value of the antenna port indicator field is a second value, DMRS ports 0 and 1 from two CDM groups may be indicated. For example, the second value corresponds to Value 1. If the value of the antenna port indicator field is a third value, DMRS ports 2 and 3 from two CDM groups may be indicated. For example, the third value corresponds to Value 2. If the value of the antenna port indicator field is a fourth value, DMRS ports 0 and 2 from two CDM groups may be indicated. For example, the fourth value corresponds to Value 3.
Optionally, in this embodiment of this application, when the first DMRS port determined in 1) above includes a plurality of DMRS ports from different code division multiplexing (CDM) groups, the terminal may determine that the uplink transmission thereof is associated with a plurality of target objects and perform the uplink transmission on the plurality of target objects by using the plurality of DMRS ports.
Optionally, in this embodiment of this application, when the first DMRS port determined in 1) above includes a plurality of DMRS ports from a CDM group, the terminal may perform one of the following:
Optionally, in this embodiment of this application, when the scheme used for the uplink transmission of the terminal is FDM and the uplink transmission corresponds to a plurality of DMRS ports from different CDM groups, odd-numbered subcarriers and even-numbered subcarriers of frequency domain resources of the uplink transmission are associated with different target objects. Additionally/alternatively, when the scheme used for the uplink transmission of the terminal is FDM and the uplink transmission corresponds to a plurality of DMRS ports from a same CDM group, different physical resource blocks of the frequency domain resources of the uplink transmission are associated with different target objects.
For example, if the network side configures the transmission scheme of FDM for the terminal through RRC signaling, when a DMRS port indicator of the PUSCH transmission is {0, 2}, odd-numbered subcarriers of frequency domain resources of a PUSCH correspond to one TCI state (panel), and even-numbered subcarriers correspond to another TCI state (panel). If the PUSCH transmission indicates a plurality of DMRS ports from a CDM group, a first PRB of the frequency domain resources of the PUSCH is associated with one TCI state 1 (panel), and a second PRB is associated with another TCI state (panel).
Optionally, in this embodiment of this application, if the scheme used for the uplink transmission of the terminal is FDM or a single frequency network (SFN) and is associated with a plurality of target objects, the DMRS port for the uplink transmission may be determined by at least one of the following:
Optionally, the third DMRS port includes: a plurality of identical DMRS ports in one-to-one correspondence to the plurality of target objects, that is, a plurality of identical DMRS ports respectively corresponding to the plurality of target objects.
In some embodiments, in the FDM scheme, if transmission of the terminal associated with a plurality of target objects has a code word (CW), the terminal may determine, according to the rank indicated by the target TPMI field received, the third table for interpreting DMRS ports.
In some embodiments, the above target TPMI field is the first TPMI field received by the terminal.
In some embodiments, the above target TPMI field may be carried in DCI, which is sent by the network-side device to the terminal.
In some embodiments, when the terminal determines the third DMRS port for the uplink transmission according to the third table, specifically, the third DMRS port for the uplink transmission is selected from the third table according to an antenna port indicator field received by the terminal. That is, the third DMRS port is a DMRS port in the third table indicated by the antenna port indicator field.
For example, if the rank indicated by the target TPMI field is 2, the third table may be, but is not limited to, shown in Table 3 below:
Optionally, the fourth DMRS port includes at least one of the following: a plurality of DMRS ports corresponding to a first target object, and first M DMRS ports of a plurality of DMRS ports corresponding to a second target object; where the first target object corresponds to the maximum value in the plurality of ranks, the second target object corresponds to any other rank in the plurality of ranks except the maximum value, and M is determined based on a rank indicated by a TPMI field and corresponding to the second target object.
In some embodiments, in the FDM scheme, if transmission of the terminal associated with a plurality of target objects has a plurality of CWs, the terminal may determine, according to the maximum value in the plurality of ranks indicated by the plurality of TPMI fields received (e.g., all the SRI fields received), the fourth table for interpreting DMRS ports.
In some embodiments, when the terminal determines the fourth DMRS port for the uplink transmission according to the fourth table, the plurality of DMRS ports corresponding to the first target object may be selected from the fourth table according to a received antenna port indicator field, and first M DMRS ports of the plurality of DMRS ports are determined to be ports corresponding to the second target object. That is, the first target object corresponds to the DMRS ports in the fourth table that are indicated by the antenna port indicator field, and the second target object corresponds to first M DMRS ports of the DMRS ports in the fourth table that are indicated by the antenna port indicator field.
For example, the uplink transmission of the terminal is associated with two target objects, i.e., a 1st target object and a 2nd target object, which respectively correspond to a first TPMI field and a second TPMI field. If a rank indicated by the first TPMI field is x, a rank indicated by the second TPMI field is y, and x>y, the fourth table for interpreting DMRS ports is determined according to x.
It is to be noted that, in this embodiment of this application, the target object involved is parameters related to uplink data transmission. For example, the target object may include, but is not limited to, a beam, a transmission and reception point (TRP), an antenna panel, a transmission configuration indicator (TCI) state, a TCI state pool, a spatial relation, a sounding reference signal (SRS) resource, an SRS resource set, a reference signal, a path loss reference signal, and the like.

Optionally, the determining a DMRS port for the uplink transmission in step 22 may include: determining, by the terminal, the DMRS port for the uplink transmission according to a fifth table for interpreting DMRS ports, where the fifth table includes at least one first entry, and the first entry is used for indicating a plurality of DMRS ports for the uplink transmission associated with a plurality of target objects. In other words, the table for interpreting DMRS ports determined in this embodiment may include at least one first entry, and the first entry indicates a plurality of DMRS ports for the uplink transmission associated with a plurality of target objects.
For example, the above fifth table may be, but is not limited to, shown in Table 4 below:
4
2
0, 2
In Table 4, the first entry is an entry corresponding to Value 4, indicating two DMRS ports for uplink transmission associated with two target objects. That is, DMRS ports 0 and 2 are indicated.
In another example, the above fifth table may be, but is not limited to, shown in Table 5 below:

In Table 6, the first entry includes an entry corresponding to Value 12, indicating two DMRS ports for uplink transmission associated with two target objects. That is, the entry corresponding to Value 12 indicates DMRS ports 0 and 2, which are from two CDM groups.
Optionally, in this embodiment of this application, the DMRS port for the uplink transmission may be determined based on an antenna port indicator field received by the terminal. Step 22 above may include: determining, by the terminal, a fifth DMRS port for the uplink transmission according to the scheme and an antenna port indicator field received by the terminal. In other words, after the scheme used for the uplink transmission is determined, a table for interpreting DMRS ports may be first determined according to the scheme, and then the DMRS port for the uplink transmission may be determined according to the antenna port indicator field received by the terminal.
Optionally, when the uplink transmission of the terminal is associated with a plurality of target objects, the above fifth DMRS port may include: a plurality of DMRS ports indicated by the antenna port indicator field, where the plurality of DMRS ports are from different CDM groups or a same CDM group. For example, in a case that the uplink transmission adopts SDM, the plurality of DMRS ports are from different CDM groups. Alternatively, in a case that the uplink transmission adopts FDM, the plurality of DMRS ports are from a same CDM group.
For example, a bit length of the antenna port indicator field may be 3 bits or 4 bits to indicate the DMRS port for the uplink transmission. For example, in a case that the DMRS ports are interpreted based on Table 1 above, if the uplink transmission of the terminal is associated with a plurality of target objects, DMRS ports 0 and 2 in the entry corresponding to Value 4 may be indicated. Alternatively, in a case that the DMRS ports are interpreted based on Table 2 above, if the uplink transmission of the terminal is associated with a plurality of target objects, DMRS ports 0 and 2 in the entry corresponding to Value 12 may be indicated, and DMRS ports 4 and 6 in the entry corresponding to Value 13 may also be indicated
Optionally, if the uplink transmission of the terminal is associated with a plurality of target objects, the terminal may determine a plurality of DMRS ports for the uplink transmission according to a protocol definition. For example, a DMRS port group (i.e., a plurality of DMRS ports) for the PUSCH transmission associated with a plurality of target objects is agreed by a protocol, for example, {0, 2}, and a DMRS port for the PUSCH transmission associated with a target object is indicated by the antenna port indicator field. Then, when the PUSCH is scheduled to be transmission associated with a plurality of target objects, the DMRS ports for the PUSCH transmission may be determined to be 0 and 2, and the antenna port indicator field indicating the DMRS port may be ignored.
Optionally, if the uplink transmission of the terminal is associated with a plurality of target objects, the terminal may determine, according to a DMRS port indicated by the antenna port indicator field received by the terminal, a plurality of DMRS ports for the uplink transmission that include the DMRS port. For example, the PUSCH transmission is associated with a plurality of target objects, and a plurality of DMRS port groups are preset, for example, (0,2), (1,3), (4,6), and (5,7). If the antenna port indicator field received by the terminal indicates a DMRS port 0, it may be determined that the DMRS port for the PUSCH transmission includes DMRS ports 0 and 2. If the antenna port indicator field received by the terminal indicates a DMRS port 4, it may be determined that the DMRS port for the PUSCH transmission includes DMRS ports 4 and 6.
Optionally, in a case that a plurality of target objects are associated with a plurality of CDM groups one by one, that is, the plurality of target objects are respectively associated with the plurality of CDM groups, the terminal may determine, according to a CDM group to which the DMRS port for the uplink transmission thereof belongs, a target object associated with the uplink transmission. For example, a first CDM group is associated with a 1st target object, and a second CDM group is associated with a 2nd target object. Then, if only a DMRS port of the first CDM group is indicated, that is, the PUSCH transmission of the terminal belongs to the first CDM group, the PUSCH transmission is associated with the 1st target object; alternatively, if only a DMRS port of the second CDM group is indicated, that is, the PUSCH transmission of the terminal belongs to the second CDM group, the PUSCH transmission is associated with the 2nd target object; alternatively, if the DMRS ports of the first CDM group and the second CDM group are both indicated, i.e., a plurality of DMRS ports for the PUSCH transmission of the terminal are from two different CDM groups, the PUSCH transmission is associated with the 1st target object and the 2nd target object.
Optionally, if the uplink transmission of the terminal adopts a transmission scheme associated with a plurality of target objects, the transmission scheme may be enabled by at least one of the following:

A person of ordinary skill in the art may notice that the exemplary units and algorithm steps described with reference to the embodiments disclosed in this specification can be implemented in electronic hardware, or a combination of computer software and electronic hardware. Whether the functions are executed in a mode of hardware or software depends on particular applications and design constraint conditions of the technical solutions. A person skilled in the art may use different methods to implement the described functions for each particular application, but such implementation is not to be considered beyond the scope of the present disclosure.
A person skilled in the art may clearly understand that for convenience and conciseness of description, for specific working processes of the foregoing systems, apparatuses and units, reference may be made to the corresponding processes in the foregoing method embodiments, and details are not described herein again.
In the several embodiments provided in this application, it is to be understood that the disclosed apparatus and method may be implemented in other manners. For example, the described apparatus embodiment is merely an example. For example, the unit division is merely a logical function division and may be other division during actual implementation. For example, a plurality of units or components may be combined or integrated into another system, or some features may be ignored or not performed. In addition, the displayed or discussed mutual couplings or direct couplings or communication connections may be implemented by using some interfaces. The indirect couplings or communication connections between the apparatuses or units may be implemented in electronic, mechanical, or other forms.
The units described as separate components may or may not be physically separated, and the components displayed as units may or may not be physical units, and may be located in one place or may be distributed over a plurality of network units. Some or all of the units may be selected according to actual needs to achieve the objectives of the solutions of the embodiments.
In addition, functional units in the embodiments of the present disclosure may be integrated into one processing unit, or each of the units may be physically separated, or two or more units may be integrated into one unit.
When the function is implemented in the form of a software functional unit and sold or used as an independent product, the function may be stored in a computer-readable storage medium. Based on such an understanding, the technical solutions of the present disclosure essentially, or the part contributing to the related art, or some of the technical solutions may be implemented in a form of a software product. The computer software product is stored in a storage medium, and includes several instructions for instructing a computer device (which may be a personal computer, a server, a network device, or the like) to perform all or some of the steps of the methods described in the embodiments of this application. The foregoing storage medium includes: various media that may store program code, such as a USB flash drive, a removable hard disk, a ROM, a RAM, a magnetic disk, or an optical disc.
A person of ordinary skill in the art may understand that all or some of the processes of the methods in the above embodiments may be implemented by a computer program instructing relevant hardware. The program may be stored in a computer-readable storage medium. When the program is executed, the procedures of the foregoing method embodiments are performed. The foregoing storage medium may include a magnetic disk, an optical disc, a read-only memory (ROM), a random access memory (RAM), or the like.
It is to be noted that the terms “comprise”, “include”, and any other variants thereof are intended to cover non-exclusive inclusion, so that a process, a method, an item, or an apparatus that includes a series of elements not only includes these elements, but may also include other elements not expressly listed, or also include elements inherent to this process, method, item, or apparatus. Without more limitations, an element defined by a phrase “including a/an . . . ” does not exclude presence of other identical elements in the process, method, item, or apparatus that includes the element. In addition, it is to be noted that the scope of the methods and apparatuses in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing the functions in a basically simultaneous manner or in opposite order based on the functions involved. For example, the described methods may be performed in a different order from the described order, and various steps may be added, omitted, or combined. In addition, features described with reference to some examples may be combined in other examples.
According to the descriptions in the foregoing implementations, a person skilled in the art may clearly understand that the method in the foregoing embodiment may be implemented by software plus a necessary universal hardware platform or by hardware only. In most circumstances, the former is a preferred implementation. Based on such an understanding, the technical solutions of this application essentially or the part contributing to the prior art may be implemented in a form of a computer software product. The computer software product is stored in a storage medium (such as a ROM/RAM, a magnetic disk, or an optical disc) and includes several instructions for instructing a terminal (which may be a mobile phone, a computer, a server, an air conditioner, a network device, or the like) to perform the methods described in the embodiments of this application.
The embodiments of this application have been described above with reference to the accompanying drawings, but this application is not limited to the foregoing specific implementations. The foregoing specific implementations are merely schematic instead of restrictive. Under enlightenment of this application, a person of ordinary skill in the art may make many forms without departing from aims of this application and the protection scope of the claims, all of which fall within the protection scope of this application.
